'Taśma' was a Polish undertaking by the Armia Krajowa, the most important Polish resistance movement of World War II, against border outposts in German-occupied Poland (20 August 1943/February 1944).

In August 1943 the headquarters of the Armia Krajowa (home army) ordered the Kedyw (Kierownictwo Dywersji, or directorate of sabotage and diversion) ordered the Kedyw to prepare an armed action against German border guard stations on the frontier between the General Government and the territories annexed by Germany. By February 1944, 13 such German outposts had been attacked and destroyed for only modest Polish losses. One of the Poles who was killed was Tadeusz Zawadzki, one of the most important members of the Polish underground movement: Zawadzki was killed on 20 August in the course of an attack on a German border station at the village of Sieczychy, near Wyszków.

'Taśma' took place in the night of 20/21 August, when seven German stations were destroyed. On 30 August, General Tadeusz Bór-Komorowski ordered the start of preparations for another armed action as 'Lancuch' as the continuation of 'Taśma'. 'Lancuch' took place late in November 1943, units of the Armia Krajowa launching similar attacks on several German border stations in the southern part of occupied Poland. In the autumn of 1943, the Armia Krajowa element of the Kraków district attacked several German outposts along the border with Slovakia, these including those at Barwinek, Piwniczna and in the area of Nowy Targ and Wadowice.
